MooseX::AttributeHelpers::Trait::Bool - simple boolean attribute
=head1 VERSION
version 0.25
=head1 SYNOPSIS
package Room;
use Moose;
use MooseX::AttributeHelpers;
has 'is_lit' => (
metaclass => 'Bool',
is => 'rw',
isa => 'Bool',
default => sub { 0 },
provides => {
set => 'illuminate',
unset => 'darken',
toggle => 'flip_switch',
not => 'is_dark'
}
);
my $room = Room->new();
$room->illuminate; # same as $room->is_lit(1);
$room->darken; # same as $room->is_lit(0);
$room->flip_switch; # same as $room->is_lit(not $room->is_lit);
return $room->is_dark; # same as !$room->is_lit
=head1 DESCRIPTION
This provides a simple boolean attribute, which supports most of the
basic math operations.
=head1 METHODS
=over 4
=item B<meta>
=item B<helper_type>
=item B<method_constructors>
=item B<has_method_provider>
=item B<method_provider>

=head1 PROVIDED METHODS
It is important to note that all those methods do in place
modification of the value stored in the attribute.
=over 4
=item I<set>
Sets the value to C<1>.
=item I<unset>
Set the value to C<0>.
=item I<toggle>
Toggle the value. If it's true, set to false, and vice versa.
=item I<not>
Equivalent of 'not C<$value>'.
